Linked Reviews
Tax

Di Tanno Associati, founded in 1986, provides consultancy services based on financial acumen and corporate law integration. Transactional tax, tax controversy, real estate, litigation, private clients, corporate tax, international tax, tax planning and transfer pricing are all areas of expertise for the firm. Tommaso Di Tanno, the firm's founding partner, leads a team of 11 partners.

Case studies show that the firm assisted Vodafone Italia in its Supreme Court dispute against the Italian Tax Authority. The dispute centred on the calculation of the tax owed for the release of the revaluation credit balance, which was discernible in its ‘net’ book value. The team also represented Enel in a significant dispute with the Revenue Agency (the Italian tax authority) over the correct valuation of a wind farm's cadastral income before the Supreme Court.

Partners Raffaele Villa and Luca Marraffa joined the firm from CBA Studio Legale e Tributario and EY during the research period. At the same time, partner Paolo Serva departed the firm.

Client feedback

“Entrepreneurial mindset, thinks like an investor, solution oriented.”

“Strong commercial sense (thinks like an investor), ability to work independently with counterparties, great customer standing.”

“Di Tanno e Associati has great expertise and is able to effectively represent and defend the company in the pre-litigation phases and during the tax dispute.”
